Effect of CP and A/S on GLT-1, xCT and GLAST expression in the dorsomedial prefrontal cortex (dmPFC). (A, C, E) Immunoblots for GLT-1/ β-tubulin, xCT/ β-tubulin and GLAST/ β-tubulin, respectively. (B) Statistical analysis revealed a significant upregulation of GLT-1 expression in CP-A/S treated group as compared to CP-Vehicle group. (D) xCT expression was downregulated in CP-Vehicle group as compared to Vehicle-Vehicle and CP-A/S groups. (F) Statistical analysis of GLAST expression revealed no change among all groups in the dmPFC. (*p < 0.05, **p < 0.01 and ***p < 0.001), (n = 6-7 for each group), values shown as means ± S.E.M, (V: Vehicle; A/S: Ampicillin/Sulbactam; CP: CP 55,940).
